Gas inserts are typically the most efficient option (70–90% efficiency vs. 10–20% for open wood-burning fireplaces). Pellet inserts also offer high efficiency (75–90%). For Denver's climate, gas inserts provide the best combination of efficiency, convenience, and heat output during the November–March heating season.
A fireplace insert installation typically takes one full day (4–8 hours). A new masonry fireplace takes 3–7 days depending on design complexity. We always provide a clear timeline estimate before beginning work.
